The course is in the shape of a massive 'U', 320 metres in length, between 0.8 and 1.2 metres deep and between eight and 12 metres wide. The overall drop from top to bottom is 5.5 metres. During events a conveyor belt is used to take boats, and their occupants, from the finishing pool back to the start.

As the course has been built in a relatively flat area (flood plain), it has been built up and landscaped to create the sloping course necessary for the required rapids. Five of the six available 300-kilowatt pumps lift the water from the bottom to the start of the course, at the rate of 14 m³/s.

The channel is constructed from concrete with sloping sides. By setting river pebbles into the concrete an effect to make the course look like a natural river has been created. Large immovable rocks shape the course, as well as movable obstacles which may be used for varying the difficulty of the course and for fine-tuning of the rapids.

The facility, which includes a cafe, is a popular recreational area, offering large rubber raft rides, as well as individual kayaking/canoeing. It is regularly used for local, national and international canoeing/slalom events. It is accessed via McCarthys Lane, which runs off Castlereagh Road, Cranebrook.
